BLIND: A Complete Identity Protection Framework for End-Points

In this paper, we present a security framework that provides identity protection against active and passive attacks for end-points. The framework is based on a two-round-trip authenticated Diffie-Hellman key exchange protocol that identifies the end-points to each other and creates a security association between the peers. The protocol hides the public key based identifiers from attackers and eavesdroppers by blinding the identifiers. We complete the identity protection by offering location privacy with forwarding agents. To our knowledge, our privacy enhanced protocol is the first denial-of-service resistant two-round-trip key exchange protocol that offers identity protection for both communicating peers.
